Abstract
An outer envelope trochoidal device is provided. The device includes a rotor shaft and rotor assembly, the rotor assembly having a peripheral surface that defines a trochoidal curve and includes a first and a second rotor half. Each rotor half has a trochoidal profile surface and an inner circular surface. The rotor shaft includes secured thereto a cylindrical sleeve that includes a radial flange to which at least one of the rotor halves is secured. The rotor halves are secured to each other by counterbolt means extending laterally through the rotor halves. One rotor half can include a tapped hole in the outer peripheral surface of the rotor and a channel extending from the end of the tapped hole to the sleeve on the rotor shaft. A chamber is defined by a portion of the sleeve and a portion of the rotor half pinned to the sleeve, the chamber being in fluid communication with the channel. When a fluid under pressure is injected into the channel and thereby the volume through the tap hole, the rotor halves are caused to separate and disengage the rotor shaft.
